Rotate multiple pdf/a files using Adobe Acrobat Pro

[markvoltz]

I have about 100 pdf files that I need to rotate to the left by 90 degrees.  I presume many if not all of them are stored in PDF/A mode a.k.a. PDF/Archive mode.  I have a workflow to rotate pdf/a files using my copy of Adobe Acrobat Pro version 9 however, the workflow I have is rather cumbersome.

1. Open the pdf/a file in Adobe Pro 9
2. Go to Advanced -> Preflight -> pdf/a -> Remove pdf/a.
3. Save the pdf - so that it is no longer in pdf/a mode.
4. Reopen the pdf file.
5. Now Adobe will let us rotate the document under Document-> Rotate Page.
6. Save the pdf - technically this should be saved as a pdf/a again.

Questions:

1. This workflow works for rotating a single pdf/a document.  However it is rather cumbersome.  Is there a quicker solution?
2. I have seen some indication that it is possible to rotate many pdf documents 90 degrees to the left at once.  However, will this work for pdf/a documents?  In addition is this feature available in Adobe Acrobat Pro Version 9?

Thanks

We found a partial answer.

You can disable pdf/a mode by going into Edit->Preferences->Documents->PDF/A View Mode.  Then change "View documents in PDF/A mode" to Never.  This significantly reduces the steps to rotate images.

1. Open the PDF file
2. Rotate the document under Document->Rotate Page.
3. Save the file.  It will automatically save as a pdf/a file.

I still don't know if there is a way to batch rotate files.  This feature might only be available in newer versions.  Let me know if batch rotating is possible in Adobe Acrobat Pro version 9

You can use a batch sequence for this.

Bear in mind that any edit to a PDF/A file will stop it being PDF/A. So it is not enough to just find a way to turn off warnings. You do specifically need to save it/preflight it BACK to PDF/A after any edit, no matter how trivial.

You might be able to use preflight to batch remove PDF/A, then make the changes, then batch convert back to PDF/A (three steps). But I'm not especially hopeful in such an old Acrobat.
